PURPOSE OF REVIEW The Gleason grading system provides important information for guiding prostate cancer patients' management and prognostication. The grading system underwent significant modifications over the past decade. In 2005 and more recently in 2014, the International Society of Urological Pathology (ISUP) held two consensus conferences to update prostate cancer grading. Recently, five p...
UNLABELLED WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: The Gleason scoring system is a well-established predictor of pathological stage and oncological outcomes for men with prostate cancer. Modifications throughout the last few decades - most recently by the International Society of Urological Pathology (ISUP) in 2005 - have attempted to improve the correlation between biopsy an...
BACKGROUND Despite significant changes in the clinical and histologic diagnosis of prostate cancer, the Gleason grading system remains one of the most powerful prognostic predictors in prostate cancer. The correct diagnosis and grading of prostate cancer is crucial for a patient's prognosis and therapeutic options. However, this system has undergone significant revisions and continues to have d...
Background: Presence of discordance between the Gleason score on needle biopsy and the score of radical prostatectomy specimen is common and universal. In this study, we determined the accuracy of Gleason grading of biopsies in predicting histological grading of radical prostatectomy specimens and the degree of overgrading and undergrading of prostatic adenocarcinoma i...
background: presence of discordance between the gleason score on needle biopsy and the score of radical prostatectomy specimen is common and universal. in this study, we determined the accuracy of gleason grading of biopsies in predicting histological grading of radical prostatectomy specimens and the degree of overgrading and undergrading of prostatic adenocarcinoma in our center, which is one...
The present study was undertaken to compare the gleason score and histologic grade of needle biopsy specimens to those of radical prostatectomy(RP) specimen to examine how accurately biopsy specimens reflect the corresponding excised specimens. In this comparative-descriptive study, gleason scoring was made on the needle biopsy specimens from 57 patients with prostate cancer and then ...
UNLABELLED THE AIM of our study was to evaluate the prognostic significance of p53 protein immunoreactivity for prostate cancer and to determine whether p53 immunoreactivity correlates with the Gleason tumor grade in primary adenocarcinoma. Prostate fragments were fixed in 10% formalin, paraffin-embedded, sectioned and standard Hematoxylin-Eosin stained, then examined using histological grade (...
PURPOSE We compared oncological outcomes according to tumor volume (TV) thresholds defining both classical and updated insignificant prostate cancer (IPC), since the TV threshold can be used as clinical parameter for active surveillance. METHODS Between 2001 and 2012, we retrospectively analyzed 331 organ-confined prostate cancer patients who had preoperative Gleason score 6, preoperative PSA...
The present study was undertaken to investigate the predictors in patients who received hormonal therapy (HT) for prostate-specific antigen recurrence (PSAR) after surgery. Predictors for the progression-free survival were assessed in 55 patients who received HT for PSAR after surgery. In multivariate analysis, primary Gleason grade > or =4 and PSA doubling time (PSA-DT) <6 months were independ...
